Hint :
The process of generating electric power from sources of primary energy is called electricity or power generation.
The power that accounts for the largest share has more than 65% of India's electricity with about 85% of the generation being coal-based.
Complete answer :
Thermal Power Plants also called “Thermal Power Generation Plant” or “Thermal Power Station”, is used to convert heat energy to electric power / Energy for household and commercial applications. To generate electric power, steam-operated turbines change the heat into mechanical power and then finally electric power.
More than 65% of India's electricity generation capacity comes from thermal power plants, with about 85% of the country's thermal power generation being coal-based.
Thermal energy accounts for the largest share of power generations in India. Currently, the biggest thermal power plant in India is the Vindhyachal Thermal Power Station in the Singrauli district of Madhya Pradesh. The power plant is coal-based, owned and operated by NTPC.
Additional information:-
Nuclear power plants
Nuclear power plants generate high amounts of electricity using nuclear fission reactions and uranium as a fuel. It is the fifth-largest source of electricity in India.
As greenhouse gas emissions are low, the energy is considered environmentally friendly.
The power generation from nuclear power plants is considered more reliable as compared to renewable sources of energy such as solar and wind
Nuclear energy sources produce enormous amounts of power in a low quantity of fuel due to higher density than fossil fuels, making them efficient.
Hydroelectric power plants
The gravitational force of flowing water is utilized to produce hydroelectricity.
Hydroelectric power plants emit fewer greenhouse gases in comparison to fossil fuel-powered energy plants.
Solar power plants
Solar energy plants convert the sun’s energy into thermal or electrical energy. It utilizes one of the most abundant renewable energy sources.
It accounts for 3.6% of the total power generation in India.
High maintenance is not generally required and lasts for about 20-25 years.
Option D , is the correct answer.
Note :
Although Thermal power plants account for the largest share of power generation still it has certain disadvantages that cannot be neglected.
They affect the environment due to the production of a large amount of smoke and fumes.
The overall efficiency is low.
Expensive to maintain
A large quantity of water is required for maintaining the temperature of the turbines.
